Description

Technical Field

[0001] The invention relates to an evaporative air cooler. Background Art

[0002] Evaporative air conditioners use the principle of water evaporation and heat absorption to achieve rapid cooling. Compared with traditional air conditioners, they consume less power and use water as a refrigerant, which is environmentally friendly and pollution-free. With the improvement of people's living standards and the enhancement of environmental awareness, evaporative air conditioners are becoming more and more popular among consumers due to their advantages of energy saving, environmental protection, health and comfort.

[0003] Since the evaporative air conditioner uses wet curtains to absorb heat by evaporating water to cool the air, and the wet curtains are in contact with water for a long time, mold and mildew will appear inside the wet curtains over time. If not discovered in time, it will affect the output air quality; and due to the special structure of the wet curtains, even if there are mold and mildew inside the wet curtains, it is not easy to be discovered. At the same time, since the evaporative air conditioner, especially the evaporative air conditioner used in workshops and factories, is exposed to the outdoors for a long time, the filter will be blocked by dust after a long time of use. Since the evaporative air conditioner is installed outside the factory, it is inconvenient for personnel to check. If the blockage is not discovered in time, it will also affect the output air volume of the evaporative air conditioner. In addition, the evaporative air conditioner is large in size and needs to occupy a relatively large space during transportation, which limits the transportation volume of a single vehicle / cabinet, and invisibly increases or decreases the transportation cost.

Detailed implementation manners

[0020] To make the above features and advantages of the present invention more understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0021] Reference Figures 1 to 11 An evaporative air conditioner includes a top cover 100 and a base 200 with an air duct 210 disposed in the middle. A water receiving tray 201 is formed between the outer wall of the air duct and the side wall of the base inside the base. Side plates 300 are installed around between the base and the top cover. A wet curtain 400 is disposed inside the side plates. At least one transparent observation tube 410 is embedded in the middle or lower part of the wet curtain. The outer end of the observation tube penetrates into the side plate and is installed with a convex lens 411. The inner end of the observation tube is sealed with a reflector, or a camera with illumination light is installed in the observation tube, and the camera is a micro camera. Through the cooperation of the convex lens and the observation tube, the usage condition of the wet curtain can be observed manually to check whether mildew occurs inside the wet curtain. Or the observation tube is observed through the camera. The camera is electrically connected to the controller, and the captured image is transmitted to the controller, and it is judged whether the wet curtain has mildewed through the image, so that the user can replace the wet curtain as soon as possible.

[0022] In this embodiment, support columns are fixed at the four corners between the base and the top cover, and the side plates are installed between adjacent two support columns, so that an air cooling and cooled air accommodating cavity is formed by enclosing the base, the top cover, the side plates and the support columns for the air duct to suck.

[0023] In this embodiment, the side plates are evenly distributed with air inlet slots 301. The lower end of the partition 310 between two adjacent air inlet slots inclines downward, and the upper surface of the partition is smooth, so that the dust falling on the partition can slide down automatically, reducing the amount of dust contamination on the partition.

[0024] In this embodiment, an air filter 320 is installed in the area on the side plate between the air inlet slot and the wet curtain. The air filter can adopt a multi-layer filter design, including a primary filter, an activated carbon filter and a HEPA filter, which helps to filter pollutants such as dust, pollen, PM2.5, etc. in the air.

[0025] In this embodiment, the outer end of the observation tube passes through the filter and extends into the air inlet slot. A sealing structure is provided between the observation tube and the filter to prevent pollutants from entering the wet curtain through the gap between the observation tube and the filter.

[0026] In this embodiment, a water supply pipe 220 is provided on the base. An inlet valve is installed on the water supply pipe. A vertically downward filter pipe 221 is installed at the output end of the inlet valve. A barrel-shaped filter screen 222 is installed in the filter pipe, and a gland 223 that abuts against the upper end of the barrel-shaped filter screen is installed at the upper end of the filter pipe. Thus, the input water is filtered to filter impurities in the water. The inlet valve is connected to the controller, and a water level sensor is also provided in the water receiving tray, so that when the water level is too low, the inlet valve is controlled to open to achieve automatic water replenishment.

[0027] In this embodiment, a high-foot pump 230 is provided in the base. Four output pipes 240 are connected to the output pipeline of the high-foot pump, and each output pipe is respectively connected to a water distributor 110 installed on the upper side of the wet curtain. A sterilization device 250 is provided on the output pipeline to sterilize the water extracted from the water receiving tray, which helps to further improve the quality of the air output by the air conditioner.

[0028] Specifically, the sterilization device includes a sterilization pipe 251. A waterproof sterilization lamp 252 is provided in the sterilization pipe. A water inlet pipe 253 connected to the output pipeline is provided on the side wall of one end of the sterilization pipe, and a water outlet pipe 254 is radially provided on the side wall of the other end of the sterilization pipe. Thus, the liquid input from the water inlet pipe is sterilized by ultraviolet rays through the sterilization lamp, and then output to the output pipe through the water outlet pipe.

[0029] In this embodiment, in order to connect the air duct with the base and simplify the forming difficulty of the air duct and the base, a circular seat 260 is provided in the middle of the base. Three convex blocks 261 are arranged at intervals along the circumferential direction on the outer wall of the circular seat. Three U-shaped convex parts 211 corresponding to the outer side wall of the air duct along the circumferential direction are provided, and the bottoms of the U-shaped convex parts are connected to the convex blocks by bolts 262. A block 212 that seals the upper end of the U-shaped convex part is installed along the upper end of the air duct. Thus, the forming difficulty of the air duct is simplified, and the notch on the air duct is sealed by the block to improve the aesthetics of the air duct.

[0030] In this embodiment, in order to better achieve the connection between the insert and the C-shaped protrusion, step surfaces 213 are provided on both sides of the upper end of the C-shaped protrusion, and slots 214 are provided on the step surfaces. The lower end of the insert is provided with a limiting flange 215 located on the inner side of the C-shaped protrusion, and hook plates 216 passing through the slots are provided on both sides of the insert.

[0031] In this embodiment, when the evaporative air cooler is transported, in order to reduce the occupied space and increase the transport capacity of a single vehicle, the side panels and wet curtains are disassembled, and a mounting seat 500 is configured. The mounting seat is detachably connected to the four corners of the base and the top cover through screws 501. The mounting seat has a sleeve 510. A support rod 520 with an end inserted into the sleeve is arranged between the corresponding mounting seats between the base and the top cover. The sleeve is radially provided with screws 511 for locking the support rod. In this way, the height of the air cooler can be reduced to 1 / 2 of the height of the whole machine after assembly.

[0032] In this embodiment, the height of the support rod is 2-4 cm greater than the distance between the top of the motor and the upper end surface of the base after the motor 217 is installed on the wind tube, so as to avoid the bottom surface of the top cover from contacting the top surface 4. The bottom surface of the top cover is provided with staggered circular reinforcement ribs and X-shaped reinforcement ribs 101, so as to improve the strength of the top cover. The bottom surface of the top cover is also provided with a positioning rib plate 102 for cooperating with the water distributor to complete the positioning of the water distributor.

[0033] In this embodiment, a PM2.5 sensor 270 and an airflow sensor 280 are installed in the air outlet in the middle of the base to monitor the concentration of particulate matter in the air and the change of wind speed in real time. The PM2.5 sensor and the airflow sensor are connected to the controller, so that the detected structure is fed back to the controller so that the detected data can be compared with the lowest value that can be used. If it is less than the set value, the customer is reminded to clean or replace the filter, which helps to ensure the efficient operation of the machine. Or according to the PM2.5 data and airflow data, the algorithm is used for analysis to determine the degree of blockage of the filter and calculate the remaining service life of the filter. When the filter reaches the level that needs to be replaced or cleaned, the controller will display a prompt message and emit a beep to remind the user. At the same time, the air quality detected by the PM2.5 sensor can also help to determine whether there are mildew spots on the water curtain, which can better meet the user's needs for air quality and intelligence.

[0034] In this embodiment, the evaporative air cooler can also support APP remote control, so that the status of the air conditioner can be controlled anytime and anywhere.

[0035] The above description is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, designing different forms of evaporative air coolers does not require creative labor. Without departing from the principles and spirit of the present invention, all equal changes, modifications, substitutions and variations made within the scope of the patent application of the present invention should fall within the scope of the present invention.
